Wiki B12 injections

Payers need the drug code in addition to the injection code in order to determine whether or not the injection is a covered benefit. If the patient (or another outside source) provided the drug, the usual practice is to bill the drug with a $0.00 or $0.01 charge to indicate that there was no cost to the provider incurred for the drug itself and that you are not seeking reimbursement for that portion.
